Solve this instance: Passage: With a budget of $230,000, the surviving original lunar broadcast data from Apollo 11 was compiled by Nafzger and assigned to Lowry Digital for restoration. The video was processed to remove random noise and camera shake without destroying historical legitimacy. The images were from tapes in Australia, the CBS News archive, and kinescope recordings made at Johnson Space Center. The restored video, remaining in black and white, contains conservative digital enhancements and did not include sound quality improvements. Question: Were the tapes able to be restored and processed without destroying historical legitimacy or did some aspects of the tapes lose legitimacy?
Student:
without destroying historical legitimacy
